The invention discloses a reservoir
flood control limit
water level dynamic adjustment method based on forecast error override
fortification. The method comprises the steps of 1, realizing rainfall forecast grading; 2, determining an override control rainfall threshold; 3, obtaining rainfall forecasting grade information in the next 24 hours and judging whether the rainfall forecasting grade in the next 24 hours is a rainfall forecasting grade of
light rain or below; 4, dynamically adjusting reservoir
flood control limit
water level of the rainfall forecast levels of the
light rain and below the
light rain; and 5, dynamically adjusting the reservoir
flood control limit
water level of the moderate rain and
precipitation prediction grade above the moderate rain. According to the method, thereservoir is protected according to the condition that the average areal rainfall on the
drainage basin is equivalent to the forecast override rainfall; the corresponding safety limit water level is reversely deduced according to the reservoir flood control capacity and the safety
discharge control flow, the flood control water level is deduced on the basis of rainfall forecasting, the possible
precipitation value range is expanded in an override mode while the forecasting precision is considered, the utilization of flood resources by the reservoir is increased, and the
flood regulation risk of the reservoir is reduced.
